If during a Sim session you could smell smoke, would you don the mask and run the drill, assuming these things are getting more realistic by the day... or would you perhaps pause and contemplate if the bloody simulator was actually on fire?
Done incapacitation drills more times than I care to count, some less straight forward than others, but never once did the Pilot feigning death attempt to win an Oscar.
No matter how hard some checkies try to simulate the real world, the fact is, simulators are just that.
